DTC Descriptors

DTC B3669 01
- Deck Lid Position Sensor Circuit short to battery

DTC B3669 06
- Deck Lid Position Sensor Circuit short to ground or open

DTC B3669 58
- Deck Lid Position Sensor Circuit incorrect reaction after event

Circuit/System Description

S2 is the Rear Compartment Cylinder Extended Sensor. The folding top control (FTC) module uses S2 to determine the position of the deck lid while in the reverse open position. S2 is a hall effect sensor that becomes active when the deck lid is in the reverse open position.

Conditions for Running the DTC

The FTC module is active.

Conditions for Setting the DTC

A short to ground, short to voltage, or open is detected on the signal circuit of S2.

Action Taken When the DTC Sets

The top is disabled.

Conditions for Clearing the DTC

The fault is no longer present and the top completes one cycle.

Diagnostic Aids

A weak battery may cause DTC B3669 58 or DTC B3669 59 to set.

Circuit/System Testing

1. Disconnect the harness connector at S2.
2. Probe the 12-volt reference circuit terminal 2 with a test lamp connected to ground. The test lamp should illuminate.

^ If the test lamp does not illuminate, test for an open or short to ground.
^ If circuit OK, replace FTC module.

3. Probe the signal circuit terminal 1 with a test lamp connected to B+. The test lamp should illuminate.

^ If the test lamp does not illuminate, test for an open or short to voltage.
^ If circuit tests OK, replace FTC Module.

4. Test the signal circuit for a short to voltage. Repair as necessary.

^ If no short to voltage is found, replace S2.
